No key buzzer or dome light.

[Racer57]

Haven't paid attention to them until now. So I don't know if they both quit same time or not. Buzzer doesn't work and the dome light doesn't come on with either the door switch or dash light knob. The fuses have been swapped out for new, even though they tested good. Is there a connection with the two ?  Any ideas where to start ?

Just looking at the schematic the timed delay ground appears to be one thing in common if your model is so equipped

I was bench testing some key-in buzzers the other day, here's how you can tell if they work.

Seems those damn things almost never go bad though
